Stressing slab post tensioning Flat Anchorage for 5 Strands Wedge

A core component for post-tensioning systems, the 5-Strand Wedge Flat Anchorage is tailored for thin concrete structures. It anchors 5 steel strands via wedge clamping, ensuring efficient prestress transmission with compact design, reliability and wide adaptability.

I. Structure & Working Principle

The system includes a flat anchor plate (5 parallel holes), wedge clips, bearing plate and spiral reinforcement (optional corrugated pipes). It fits 12.5-15.7mm steel strands, neatly placed in flat ducts.

Strands are tensioned individually; wedge clips grip strands tightly for self-anchoring. Prestress is evenly transferred to concrete, with spiral reinforcement preventing cracking. Anchoring efficiency ≥0.95, meeting standards.

II. Key Advantages

1. Compact & Space-Saving

Flat design reduces space, ideal for height-restricted projects (bridge decks, basement roofs) with uniform stress distribution.

2. Reliable Anchoring

40Cr anchor plate (HRC 50-60) and high-hardness clips (HRC 50-65) resist retraction, supporting complex tensioning processes.

3. Easy Installation

Compatible with conventional equipment, it allows flexible tensioning. Grouting holes prevent corrosion, boosting efficiency.

4. Wide Adaptability

Compliant with global standards, it suits bridges, buildings and dams. Precision treatment controls friction loss ≤6%.

III. Applications

- Bridges: Transverse prestressing, box girders, hollow slabs;

- Buildings: Prestressed floors, underpasses, basements;

- Special Projects: Dam panels, ports, slope anchoring.
